Standards of hydraulic hose fittings
Rubber hose has become an indispensable accessory in the fields of chemical, petrochemical and pharmaceutical industries as well as in the transportation and production of automobiles, tankers, tankers and ships: such as high temperature, low temperature, wear, bending, folding, pulling , pressure and chemical corrosion, etc. However, these harsh conditions and improper user methods have always been a serious problem.
Process line for rubber hoses in the chemical industry
Rubber hoses serve as connections between machines or instruments. It can also transport various liquids according to its structure and design. Therefore, rubber hoses must undergo strict inspection. Then inspect the features of rubber pipe. In order to make a good hose, the rubber hose suppliers set up complete process line. There should be an inspection record before the delivery. While it should contain structure, production and inspection dates of the hose. In order to be responsible to users, you should also record problems that arise during the production. Especially the problem that occurs in the transfer of steam and corrosive liquids. However, rubber hoses are not suitable for certain usage due to improper user methods. Even no damage to the hose was found. But it is still necessary to know why solvents can damage the inner and outer layers of rubber tube.
In addition, you can only operate it after confirming the rubber hose can withstand folding, bending, impact and wear. In addition to permeability and pressure, length changes and diameter are equally important. Moreover, the time and service life of industrial hoses in contact with liquid must be accurate. All these parameters are fairly easy to determine. It is also necessary to know whether the hose can withstand vacuum. Because the hose will work under vacuum. In this case, there should be reinforce layer inside the rubber pipe. In general, the reinforce layer is steel wire.
